帮朋友问一下： function autochange()
{
var Time = new Date ( );
var Hour = Time.getHours ( );
var bg_array = new array(2);
var mask_array = new array(2);
var i = 0;
bg_array[0] = "bg1.png";
bg_array[1] = "bg2.png";
mask_array[0] = "Overlay1.png";
mask_array[1] = "Overlay2.png";
i = ( Hour > 12 ) ? 1 : 0;
}
这段时间判断的javascript中 两个数组bg_array[i]以及 mask_array[i]要如何传递到<img src = "xxx" >中？让xxx从数组中获得路径实现定时更换图片？

<style>问题是 前后两处src指向的路径都是一致的，可是后面的那段代码死活都是显示红X还有哪里需要修改么？

[/code]这段代码是跟着上面那段的，发现只要把代码结束的那个</style>删除 图片就正常了。。求解 -_-# 不过会导致下面的function无效。求解
